There seems to be a bit of confusion involving the Nordstorm sale. I followed and it seems as if you have to be a level three card member (spend over $10,000 annually on your Nordstrom card) to receive the additional discount.
Here are some discount examples sent to me by witnessed other Mad-Spies:
Chanel is 40% off
Marc Jacobs 40% + 30%
Gucci bags 40% + 30% off
Fendi 40% + 30%
Don’t worry. We’ll get to the bottom of this!
